Rohde & Schwarz HX002H2 Dipole Antenna 1.5 MHz – 30 MHz
Description
Rohde & Schwarz HX002H2 150 W HF Dipole Antenna 1.5 MHz – 30 MHz is suitable for setting up radio links over any distance. In particular, the optimized omnidirectional coverage ensures high transmission reliability over short and medium distances.
The antenna enables silent tuning over the entire frequency range from 1.5 MHz to 30 MHz. The integrated tuning unit must first learn the correct tuning settings for the antenna in a user-defined frequency range. The antenna then achieves tuning times of < 5ms.
The integrated antenna tuning unit is protected against direct lightning strikes and was tested with 10 kV/10 kA discharges.
Features
- Optimized for the use onboard ships
